Detailed description of the invention
Fig. 1 is satellite power supply and distribution test equipment General design method flow diagram of the present invention；
Fig. 2 is interconnecting module schematic diagram of the present invention.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments:
It is as shown in Figure 1 satellite power supply and distribution test equipment General design method flow diagram, a kind of satellite as seen from the figure
Face power supply and distribution test equipment General design method is as follows:
Step (1) determines that the configuration satisfaction of satellite power supply and distribution test equipment resource is grinding satellite to ground power supply and distribution test
Equipment simulating amount inputs the quantity of the DO of AI, digital quantity input DI and digital output；
For digital quantity input DI quantity it is different from interface form, comb it is all grind satellite be directed to digital quantity input DI connect
The greatest requirements of mouth quantity；
Being set in and grinding both-end voltage acquisition digital quantity input DI interface quantity on Satellite is L, i.e. ground installation digital quantity
The number for inputting DI is L, and wherein in the road L ground installation digital quantity input DI, every road configures solid-state relay and is isolated.；
It is M that ground checkout equipment, which provides power supply and carries out on off operating mode monitoring acquisition digital quantity input DI interface quantity,；Ground test is set
It is N that standby internal acquisition digital output DO instruction transmission state, which carries out the interface quantity of the digital quantity input DI of back production,；
It sets on star and the interface total quantity of ground acquisition digital quantity input DI is S；Then equipment internal digital amount inputs DI
Resource distribution is as follows: both-end voltage digital quantity input DI acquisition quantity required is P=L* (1+80%) on star, needs ground test
The digital quantity input DI collecting quantity that equipment provides power supply progress on off operating mode monitoring is configured to Q=M+1, to ground installation inside
Acquiring digital output DO instruction transmission state and carrying out the digital quantity input DI configuration quantity of back production is R=S-L* (1+80%)-
(M+1), it and R >=N* (1+80%), maximizes to realize, be flexibly utilized by device resource, inside the equipment between each DI access
Independent, i.e., between each other without any connection relationship, each model can be attached in cut cable as needed, configure；
Step (2), statistics are all in the digital output DO greatest requirements quantity for grinding satellite, the number that equipment is finally equipped with
Word amount exports DO quantity and configures quantity phase with the digital quantity input DI for carrying out back production to ground installation inside DO instruction transmission state
It together, is all R；
Configuration magnetic latching relay is ground electricity inside the digital output DO amount R that equipment is finally equipped with, including equipment
Source, which is broadcast TV programs by satellite, provides the DO number of passages B of configuration electromagnetic relay inside the DO number of passages A and equipment of supply access；Each control is logical
It is mutually indepedent between road, no any connection relationship；Digital output DO amount R=A+B that equipment is finally equipped with.
Step (3), due to each satellite power index it is different, thus to power supply on-off relay contact rated current requirement
Difference, since power supply on-off relay is not pluggable relay, common apparatus devises switching model that can be easy to disassemble
Block is installed on interconnecting module come the maintenanceability realized that equipment room is general and improve equipment, welds 2 2JB-30 type magnetic holdings
Relay simultaneously increases a Y2-50 type connector, and it is (defeated from equipment power supply interface which contains power supply input positive line simultaneously
Enter) and output line (to plant capacity output interface after the control of magnetic latching relay contact), the conversion for main track of powering
It is connect when magnetic latching relay damages or be unsatisfactory for the requirement of satellite current-carrying capability as long as pulling up this with the switching with external interface
Plug-in unit removes interconnecting module, replaces spare or newly grinds interconnecting module, then plugging Y2-50 type connector can be according to relative program
Continue to execute test；
Wherein the end KT1 of 1 2JB-30 type magnetic latching relay is connect with the end Vcc1 of Y2-50 type connector；Another,
The end KT2 of 2JB-30 type magnetic latching relay is connect with the end Vcc2 of Y2-50 type connector；The end GD of Y2-50 type connector with
External pressure stabilizing power supply module connection.
Step (4) draws the passive contact of driving power and electromagnetic relay inside power supply and distribution test equipment simultaneously
To equipment output interface, each satellite can be completed according to the specific design of power-supply controller of electric on star by the special designing of cable plug
The conversion of control mode；
It can be seen that first two situation is required to 28V electricity inside ground power supply and distribution test equipment at present altogether there are three types of connection type
Source power supply, the first situation battery make to can control 28V main track on-off, and battery leads to and the disconnected control 28V negative wire on-off of battery, and second
Situation battery makes to can control 28V negative wire on-off, and battery is logical and the disconnected control 28V main track on-off of battery, the third situation do not use ground
Face 28V power supply, Cell On-Off relay use satellite bus power supply power supply (situation)
28V positive and negative wire, battery are enabled simultaneously, battery is logical, the disconnected control relay of battery exports passive contact two
End leads to power supply and distribution test equipment DO output interface, and each model can design different cables to realize different control modes
(design)
Step (5) is planned as a whole grinding satellite wired analog amount input AI,
It sets analog quantity voltage measurement accuracy on star and is better than 25mV (general measure area requirement is in -50~50V or so)
Quantity required D, analog quantity voltage measurement accuracy (generally converts electrical current into the survey of voltage better than 5mV by Hall on star
Amount, measurement range are required in -10~10V or so) quantity required be E, equipment internal electric source measurable amount is F, then equipment is most
AI (analog input) quantity configured eventually is G (generally 8 integral multiples) >=(E+1)+D* (1+30%)+F, is defended for difference
Star analog input range and measurement accuracy requirement are different, the input voltage range of extended simulation measurement circuit, and configuration -50~
The isolated amplifier of two kinds of 50V, -10~10V measurement ranges, and design interface conversion circuit, it is real according to the demand of different satellites
Existing range changes and the flexible switching of access；
Step (6), the standard interface for formulating general purpose test equipment, equipment external interface is designed as " power supply main track ",
" power supply negative wire ", " AI ", " DI ", " DO " 5 connectors, each each contact of connector and equipment internal module, resource, access
Connection relationship it is fixed, it then follows it is mutually indepedent between each access, contact, name is clear, serial number principle, it is subsequent all
Equipment interface definition must follow the standard, and each satellite power supply and distribution low-frequency cable must be also designed according to the standard interface；
Step (7), all redundancy backup AI, DI, DO and main part access are mutually independent, and resource backup both-end is independent
Output, improves the flexibility that the scalability of equipment, the utilization rate of resource and user use, master backup resource need to be in test cable
It is shorted when design.
The content that description in the present invention is not described in detail belongs to the well-known technique of those skilled in the art.
